Toptal Data Engineer interview questions

The first round is a simple introductory session where you mention which stream suits you. The second round is an online coding assessment consisting of 2 sql and 1 python questions. These were easy. The third round is a video interview(technical) with an engineer. This was the worst part of the process. 1. I was not even provided a data file. I had to copy the data from a link and put it in a file, format it as the format was horrendous. 2. Then I had to import the data file into a SQL database. I was not even mentioned the kind of IDE to use as they differ very much for SQL and Python. 3. Finally I had to solve the problem. All in 20 minutes. It felt like shooting in the dark! Worse, I was able to solve the problem in 10 minutes after I had set up a local PostgreSQL instance in my Mac.

Through video call, the first round interview with a recruiter. The next round would be a take-home coding interview. The interview question like - What was the last project you worked on? How did you contribute to it?
